Principle and application of high voltage electrostatic phenomenon

Matter is made up of molecules, molecules are made up of atoms, in which there are negatively charged electrons and positively charged protons. Under normal conditions, the number of protons and electrons of an atom is the same, and the positive and negative balance, so it is not charged externally. The reason for the unbalanced distribution of electrons is that the electrons are separated from orbit by external forces, which include various energies (such as kinetic energy, potential energy, thermal energy, chemical energy, etc.) In daily life, any two objects of different materials contact and then separate, which can generate static electricity. High voltage static electricity is widely used in our daily life, such as high voltage electrostatic precipitator. High voltage electrostatic precipitator (hvesp) is a device to collect dust in flue gas by electrostatic purification method. It is an ideal equipment for purifying industrial waste gas. Its purification work mainly depends on the discharge electrode and the precipitation electrode system.

Scale inhibition mechanism of high-voltage electrostatic circulating water treatment: the ions in water are forced to form directional movement under the influence of electrostatic field, which can not be combined and can not be close to the device wall, so as to prevent calcium and magnesium ions from reaching the device wall, so as to achieve the purpose of scale prevention and scale removal; moreover, it can play a role in stripping water scale, which can destroy the electronic binding force between scale molecules and change crystal formation in the scaling system Mechanism of control corrosion: after electrostatic treatment, the water will produce living oxygen, similar to electrolysis, this kind of active oxygen is strong, so it can produce a thin oxidation film on the clean metal surface to prevent corrosion; the mechanism of sterilization and algae killing is to interfere with the biological current of microorganisms and destroy their living environment To achieve the killing effect. The disadvantage is that the treatment effect is not stable enough and the theoretical basis is weak.
